SE WING-MACHINE Specication of Letters Patent.

Patented Feb. 4, 1908.

T o all 'whom it may concern:

Be it known that I, RcssnL G. Wooni at Waukegan, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked My invention relates to dust protectors for feeding mechanisms, and'whilc it may be used in various machines, it is more particularly adapted to machines for sewing bags. In'this class of work there is much dirt "and lint in the Vmaterial used and as it is fed l through the machine, it becomes detached from the material and lodging in the operating mechanism vbeneath the feed, causes much trouble.

The object of my invention is to provide a protector for the operating parts of the dog.

My invention consists in the novel parts, improvements and arrangement hereinafter shown and described.

In the accompanying drawings which illustrate one embodiment of my inventionz# Figure 1 shows in cross section, the for-iy ward'portion of a machine with my improvement applied thereto, certain parts beingl omitted forthe sake of clear-ness. Fig. 2 is s a top plan view of the saine with the bed plate broken away, in order to expose my protector. Fig. 3 is a perspective view of my dust protector det-ached from the machine.

The base plate l, the work support 2, the feed dog 3, the feed bar 4, the supporting frame 5 for the feed bar, and the eccentric G for raising and lowering the feed bar, are all of the usual construction, and will not be f described in greater detail. i

Secured to' the upper side of the feed bar 4, l is a rectangular plate 7, which has an openl ing S for a screw 9, whereby said plate is secured to the feed bar. This plate has at its forward end a recess 10, which engages the supporting shank 11 on the feed bar 4, which carries the feed dog 3. The feed eccentric (i, is located directly beneath the feed bar 4. This rectangular plate, secured on the upper i surface of the feed bar, extends over the feed eccentric 6, and consequently machine which are directly beneath the feed l forwardly l l any dirt or lint or the like which is detached from the material being fed to the machine by the feed dog, lodges on said plate 7, and the feed eccentric 6 is therefore, kept free from this dirt and lint.

Thilo I have shown and described my dirt protector as applied to a machine for covering and protecting the feed eccentric, it. will be obvious that said protector is equally adapted for the protection ofany other of the movingparts thatI may be located underneath the feed slot in the cloth plate. Again said protector would be useful in sewing and trimming machines to prevent loose cnds of threads from falling on and clogging the operating parts adjacent the stitching mint.

Having thus described my what I claim as new and desire Letters Patent isz- 1. In combination a feed bar, a feed dog carried thereby, means for operating said feed bar, comprising an operating part arranged beneath the' linel of feed and in the rear of the feed dog and a dust protector extending over said operating part; substantially as described.

2. In combination a feed bar, a feed dog carried thereby, means for, operating said feed bar, comprising;` an operating part, arranged bcncath the feed bar, a dust'protector secured to said feed bar, and extending over said operating part; substantially as described.

3. In (mubination, a feed bar, a feed dog carriedy thereby, means for, operating said feed bar, com )rising an operating part arranged beneat i the feed bar, and a rectangular plate having .a recess atits forward end, secured to said feed bar, and extending invention,

over said operating part; substantially as de-` to secure by.
